Abstract
A flexible tube of fabric (1) is supported by a plurality of parallel shafts (3) arranged in the tube's interior, such that a sling of fabric is suspended toward the center of the tube between two of the shafts. The shafts, or cylindrical rollers journaled thereon, rotate freely, allowing the tube to rotate. A person reclining in the sling of fabric obtains uniform body support and can easily turn over. Shaft rotation can be braked for convenient entry/exit of the occupant, with brakes designed to automatically disengage when the occupant is in the sling. The shape of the fabric tube can be varied to provide contoured body support.
